Optical Transport Network Equipment Market Global Report 2026

The optical transport network equipment market size has grown rapidly in recent years. It will grow from $22.95 billion in 2025 to $25.24 billion in 2026 at a compound annual growth rate (CAGR) of 10.0%. The growth during the historic period can be attributed to increasing deployment of fiber optic communication networks, growing investments in telecom backbone modernization, rising demand for high-bandwidth connectivity, expansion of hyperscale data center infrastructure, and increasing adoption of wavelength division multiplexing technology.

The optical transport network equipment market size is expected to see strong growth in the next few years. It will grow to $36.41 billion in 2030 at a compound annual growth rate (CAGR) of 9.6%. The growth during the forecast period can be attributed to expanding 5G transport infrastructure, increasing deployment of AI-ready data center networks, rising investments in high-capacity optical backbone upgrades, growing demand for low-latency optical connectivity, and increasing adoption of software-defined optical transport networks. Major trends during the forecast period include greater deployment of coherent optical transmission technologies, growing adoption of flexible optical transport architectures, increasing integration of high-capacity wavelength multiplexing equipment, expansion of optical network automation and orchestration, and rising demand for energy-efficient optical transmission equipment.

The rising deployment of fifth-generation (5G) infrastructure is expected to propel the growth of the optical transport network equipment market going forward. Fifth-generation (5G) infrastructure refers to the hardware and software components that power 5G networks, enabling higher data speeds, ultra-low latency, and massive device connectivity. The deployment of fifth-generation (5G) infrastructure is increasing due to the rapid expansion of IoT devices that require high-capacity, low-latency, and reliable network connectivity. Optical transport network (OTN) equipment supports fifth-generation (5G) infrastructure by providing high-capacity, low-latency fiber backhaul that efficiently transports large volumes of data between 5G base stations, edge nodes, and core networks, ensuring reliable and scalable network performance. For instance, in May 2025, according to Telefonaktiebolaget LM Ericsson, a Sweden-based information and communication technology company, 5G adoption is expanding rapidly, with subscriptions expected to reach nearly 2.9 billion by the end of 2025 and 6.3 billion globally by 2030. Therefore, the rising deployment of fifth-generation (5G) infrastructure is driving the growth of the optical transport network equipment market.

Major companies operating in the optical transport network equipment market are concentrating on developing innovative solutions, including high-degree reconfigurable optical add-drop multiplexing (ROADM) architectures, to support higher-capacity wavelength routing, enhance spectral efficiency, and enable more flexible and simplified optical network designs. High-degree reconfigurable optical add-drop multiplexing (ROADM) architectures enable dynamic wavelength routing across multiple fiber directions without requiring optical-to-electrical conversion, thereby improving network flexibility, scalability, and bandwidth efficiency. For instance, in December 2025, Ekinops SA, a France-based telecommunications technology company, launched a 32-degree reconfigurable optical add/drop (ROADM) module designed to support high-baud-rate channels and enable muxless optical network designs. The solution provides benefits including improved network scalability, enhanced spectral efficiency, and lower operational complexity. The launch is intended to help customers expand high-capacity optical transport networks while supporting the industry's transition toward more flexible, software-defined, and cost-efficient optical infrastructure.

In February 2025, Nokia Corporation, a Finland-based telecommunications equipment company, acquired Infinera Corporation for $2.3 billion. Through this acquisition, Nokia aimed to strengthen its optical transport network equipment portfolio, expand its optical networking and photonic technologies, and improve its ability to deliver high-capacity networking solutions for AI-driven data centers, cloud providers, and telecommunications operators. Infinera Corporation is a US-based company that develops optical transport networking equipment and software supporting high-capacity, long-haul, metro, and data center interconnect communications.
